    Abstract: A method and system provide an ophthalmic device. The ophthalmic device includes an ophthalmic lens having an anterior surface, a posterior surface, at least one diffractive structure and at least one base curvature. The at least one diffractive structure for provides a first spherical aberration for a first focus corresponding to at least a first focal length. The at least one base curvature provides a second spherical aberration for at least a second focus corresponding to at least a second focal length. The first spherical aberration and the second spherical aberration are provided such that the first focus has a first focus spherical aberration and the second focus has a second focus spherical aberration. The first focus spherical aberration is opposite in sign to the second focus spherical aberration.

    Abstract: A method and system provide an ophthalmic device. The ophthalmic device includes an ophthalmic lens having anterior surface, a posterior surface and at least one diffractive structure including a plurality of zones. The at least one diffractive structure is for at least one of the anterior surface and the posterior surface. Each zone includes at least one echelette having a least one step height. The step height(s) are individually optimized for each zone. To compensate chromatic aberration of eye from distance to a range of vision, a greater than 2π phase step height may be employed and the step height(s) folded by a phase, which is an integer multiple of two multiplied by π. Hence chromatic aberration of eye may be compensated to improve vision from distance to near.

    Abstract: An ophthalmic lens includes an optic comprising an anterior surface, a posterior surface, and an optical axis. At least one of the anterior surface and the posterior surface has a surface profile including a base curvature and a plurality of morphed sinusoidal phase shift structures. The base curvature may correspond to a base optical power of the ophthalmic lens, and the morphed sinusoidal phase shift structures may be configured to extend depth of focus of the ophthalmic lens at intermediate or near viewing distances.
